The Minimally Invasive TLIF technique is a less invasive option incorporating the use of specially designed instruments that allow surgeons to achieve the same clinical goals of traditional, “open” TLIF but with much smaller incisions, causing less damage to the surrounding soft tissue.

The technique incorporates use of the II Tubular Retractor System and CD II Spinal System. The METRx® II System provides minimally invasive access to the spine through tubular portals, while the CD II Spinal System uses an innovative arc device to percutaneously (without a large skin incision) deliver screws and rods for spinal fusion.

* Through a minimal incision in the patient’s back, the surgeon uses specially designed dilators in the II Tubular Retractor System to spread the muscle and tissues of the back. A tubular retractor, or “portal”, is then inserted over the dilators to maintain a clear pathway to the spine.

* Accessing the spine through the II Tubular Retractor, the surgeon removes a portion of the bone and the disc material, and places an implant in the disc space between the vertebral bodies. This spacer may serve to restore the natural height of the disc space, “unpinch” the nerves, and act as a scaffold for bone growth or “fusion” between the vertebral bodies.

* Finally, the surgeon may use the Spinal System to place screws and rods in a minimally invasive fashion. These screws and rods are intended to stabilize the vertebral bodies while the bone fuses or heals.
